Overview
This prostate biopsy procedure is performed when a
lesion is seen on ultrasound or an irregularity in the prostate
is palpated with the examining finger. An anesthetic jelly is
inserted into the rectum prior to the procedure. An antibiotic
injection or oral antibiotics are given prior to the procedure
to prevent infections. All instruments are sterile, so this is
used as a precaution. The ultrasound probe is inserted into the
rectum and 10-12 needle biopsies are obtained under ultrasound
guidance. The needles pass through the rectal wall and into the
prostate in a split second to obtain these small samples of
tissue. Very little to mild discomfort is associated with this
procedure. It is well tolerated and most men just have a dull
ache for 24-48 hours after the procedure. Oral antibiotics are
continued for three days. It is recommended that no sexual
intercourse or masturbation occur for 72 hours to allow some
healing of the fresh needle tracts. It is common to have blood
in the urine and stool for one week, which over time will
decease. Some patients will notice blood in their semen (bright
red to dark brown with time) for many months after the
procedure. Its takes quite some time to flush the prostate of
this blood. The blood will not cause any harm to your sexual
partner. We ask that you stop using any aspirin or blood
thinners 7 days before the procedure.

The prostate biopsy is a procedure that is performed
because an elevated PSA or abnormal area has been identified in
your prostate gland. It is impossible to determine the nature of
such irregularities without obtaining a small amount of tissue
with a needle biopsy for examination under a microscope. Our
goal is to determine whether these abnormalities are the signs
of an early or late stage prostate cancer. You will receive at
the minimum 10 biopsies and possibly more during this procedure.
It may need to be repeated in 3-months if negative since there
is a 20-40% reported second positive biopsy rate if the first is
negative for cancer.
****Stop all Aspirin, Motrin or blood-thinning medications
10-days prior to the biopsy. (see our list of drugs at the link
above)
****If you are taking a drug called Coumadin (warfarin), stop
taking the medication 5 days before the biopsy.
****If you have any type of foreign implant in your body from
previous surgeries please let you physician/nurse know about
this, you will need additional antibiotics the day of the
procedure that will require an injection.
****Please make sure that you have an escort with you to drive
you home from your biopsy appointment. Even though most patients
tolerate the procedure well, you will have some discomfort that
may preclude you driving home by yourself.
Day before Prostate Biopsy
You will be given a prescription for an antibiotic that
should be the day before and the morning of your biopsy. Enough
antibiotics have been given for you to continue taking them for
two more days after the biopsy. You will also have to purchase
two (2) fleets enemas at your local pharmacy. Follow the
instructions in the box and take one the evening before and one
two hours before your biopsy. You should also not eat any solid
foods after dinner the night before your biopsy. You may drink
any type of liquid that you choose right up to the point of your
biopsy. It helps to have some fluid in the bladder during the
biopsy.
Day of the Prostate Biopsy
On the day of your appointment, report to the office
where your biopsy is going to take place 15 minutes before your
appointment. You will have to provide enough urine so that we
may do a dipstick urine analysis to rule out any type of
possible infection. Do not empty your entire bladder contents
since we need some in your bladder during the biopsy. You will
be asked to remove all your clothing from the waist down except
your shoes and socks. You will be placed on your left side with
your knees brought up to your chest. A transrectal ultrasound
probe will be placed in the rectum and the prostate will be
imaged and sized. This sensation is bothersome but is usually
well tolerated by patients. The urologist will then obtain the
multiple tiny prostate samples (10 or more). The biopsy device
makes a loud noise and can startle patients; we will let you
hear this before beginning. The urologist will let you know when
he places the needle in the prostate and again when he plans to
fire the device. The tissue will be sent to a pathology lab for
evaluation which takes 5-10 working days.
After the Prostate Biopsy
After your biopsy, you will have to drink many fluids so
that you may provide us with two separate urine samples from two
separate voids. The most common complication is blood in the
urine after the biopsy. We would like to make sure that your
urine is in the process of clearing before we send you home for
the day. It is normal to see blood in the urine and bowel
movements for 1-2 weeks after the procedure. It should
progressively diminish over that time-period. If you find that,
you cannot urinate or if you are passing a large number of blood
clots, then report to the office or nearest emergency room for
evaluation. A physician may have to insert a catheter into the
bladder for a few days to allow you urine to be drained. You
should continue to drink more than your usual intake of fluids
to keep your urine diluted and to prevent formation of blood
clots within the bladder.
You may also experience a dull ache in the perineum for many
days after the biopsy. It is recommended that you halt sexual
intercourse for 3-5 days after the biopsy to allow some initial
healing. Do not be surprised if you see blood in your semen
(bight red to dark brown discoloration) after ejaculation. This
is normal and does not cause an infectious concern for your
sexual partner. This may take months to resolve. In addition,
you cannot pass along cancer to your partner via your semen
either.
If you have fever or chills, please take your temperature
with an oral thermometer and call your physician if it reads
above 100.8 F.
Follow-up
Your results will usually take 5-10 working days. If you
have not heard from your physician after 14 days please call the
office to find out why you have not yet received your results.
